DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Referring to FIGS. 1-6, an article of furniture 1 can be configured to include a shelving unit. The article can include multiple shelfs 3 that are each supported by brackets 5 that extend under a bottom surface of each shelf. A first bracket 5 can be adjacent a left side of the shelf 3 and a second bracket 5 can be adjacent a right side of the shelf 3 to support the shelf 3 in a desired, pre-selected position. For shelving units that use more than one shelf 3, there may be multiple sets of brackets 5 (e.g. a first set of brackets 5 having first and second brackets, a second set of brackets 5 having third and fourth brackets, a third set of brackets 5 having fifth and sixth brackets). Each set of brackets may support a respective shelf 3 (e.g. the first set of brackets can support a first shelf 3, a second set of brackets 5 can support a second shelf, the third set of brackets can support the third shelf 3, etc.).

The article of furniture 1 can have a top 1 b, a bottom 1 c, and lateral sides 1 d that extend vertically between the top 1 b and bottom 1 c. The top 1 b can include a top member attached to upper ends of the right and left sides 1 d and the upper end of the rear side 1 d. The bottom 1 c can include a bottom member attached to lower ends of the right and left sides 1 d and the lower end of the rear side 1 d. The front 1 f of the article can have a front opening 1 a. The front opening can be defined between spaced apart front rails 2, the bottom 1 c and the top 1 b. In some embodiments, the front opening 1 a can have a polygonal shape (e.g. rectangular, square, etc.). In other embodiments, the front opening 1 a can have a different type of shape (e.g. oval, etc.).

The rear 1 r of the article can be defined by a lateral side 1 d that defines a back or rear of the article for defining an inner cavity 1 y in which shelves 3 are positioned. The inner cavity 1 y can be defined by the top 1 b, bottom 1 c and sides 1 d. Some articles of furniture can include feet 1 e that are attached to the bottom 1 c of the article of furniture. The feet 1 e can be glides, castors, or other types of feet that support the article on a floor.

The front 1 f of the article can define the front opening 1 a for permitting access to at least one shelf 3 positioned inside the inner cavity 1 y of the body of the article that is in communication with the front opening 1 a. The body of the article that defines the inner cavity 1 y can include the sides 1 d, top 1 a and bottom 1 b.

In some embodiments, the front opening 1 a can extend from between the left side 1 d and the right side 1 d of the article. Spaced apart front rails can be positioned adjacent the left and right sides 1 d. In some embodiments, the front rails 2 can be attached to the bottom 1 c at their bottom ends 2 b and extend vertically to their top ends 2 a. Top ends 2 a of the front rails 2 can be attached to opposite ends of a front cross-member 4 that extends between upper portions of the left and right sides 1 d above the bottom 1 c.

The front of the front rails 2 can be attached to a covering to define a front vertical wall that helps define the front opening 1 a. In other embodiments, the front of the front rails can define the front vertical walls adjacent the left and right sides 1 d for defining the shape of the front opening 1 a.

Each of the front rails 2 can include a plurality of positional openings 2 p. The positional openings 2 p can be defined on a rear side of the front rails 2 that face toward the rear of the article within the inner cavity 1 y. Each front rail 2 can have multiple sets of positional openings 2 p at spaced apart locations to define different height positions for different brackets 5 for supporting a body of a shelf 3 at different positions in the inner cavity 1 y. For instance the front rail 2 adjacent the right side 1 d and the front rail 2 adjacent the left side 1 d can each include a first set 2 m of upper positional openings 2 p that are vertically aligned with each other and a second set 2 n of intermediate positional openings 2 p that are vertically aligned with each other. The second set 2 n of intermediate positional openings 2 p can be below the first set of upper positional openings. Also, the front rail 2 adjacent the right side 1 d and the front rail 2 adjacent the left side 1 d can each include a third set 2 o of lower positional openings 2 p that are vertically aligned with each other. The third set 2 o of lower positional openings 2 p can be below the second set 2 n of intermediate positional openings 2 p such that the second set 2 n of intermediate positional openings 2 p is between the first upper set 2 m and third lower set 2 o of positional openings 2 p.

Other embodiments can utilize different sets of positional openings 2 p. In some embodiments, there may be more than three sets of positional openings 2 p in each front rail (e.g. four, five, etc.). In other embodiments, there may be less than three sets of positional openings 2 p (e.g. just upper and lower sets of openings, etc.).

Each set of brackets 5 can be positioned in a corresponding set of positional openings 2 p in each front rail 2 to be positioned for supporting a respective shelf in a level orientation or other desired orientation. For example, there can be a first set of brackets 5 having first and second brackets in which the first bracket 5 is in upper positional openings of an upper set of openings in the first front rail 2 and the second bracket is in upper positional openings of an upper set of openings in the second front rail 2 so that the first and second brackets are aligned and in a parallel orientation for supporting a first shelf. A second set of brackets 5 having third and fourth brackets can be positioned so that the third bracket is positioned via a lower set of positional openings of the first front rail to support a second shelf and the fourth bracket is positioned via a lower set of positional openings of the second front rail 2 to support the second shelf. The lower positional openings of the first and second rails can have corresponding vertical positions so that the third and fourth brackets are aligned and in a parallel orientation for supporting the second shelf below the first shelf.

Some embodiments can also include a third set of brackets 5 having fifth and sixth brackets (or more than three sets of brackets and more than 3 shelfs 3). For such embodiments, the fifth and sixth brackets can be positioned in corresponding vertical positions via positional openings of the spaced apart front rails 2 at a vertical position that is between the positions of the first set of brackets and second set of brackets, or above the position of the first set of brackets or below the positions of the second set of brackets. The positional openings of the first and second rails that are utilized for attachment to the fifth and sixth brackets can have corresponding vertical positions so that the fifth and sixth brackets are aligned and in a parallel orientation for supporting the third shelf.

In yet other embodiments, there may only be a single shelf 3 supported by a single set of brackets or just two shelves 3 supported by first and second sets of brackets 5.

Each bracket 5 can include a front end 5 a that includes attachment protrusions 5 p and at least one stability projection 5 s. Each stability projection 5 s can extend laterally and each attachment protrusion can extend away from the body of the bracket for insertion into a positional opening 2 p. In some embodiments, the attachment protrusions 5 p can be shaped as hook-like elements that include a distal downwardly extending element that is positioned away from the front end 5 a of the bracket 5 by a horizontally extending portion of the attachment protrusion. The attachment protrusions 5 p can be sized and shaped for insertion into positional openings 2 p of a particular set of positional openings for attachment of the bracket to the front rail 2 as illustrating via arrows P in FIG. 6, for example.

The one or more laterally extending stability projections 5 s can extend laterally for contact with a rear face of the front rail 2 to which the bracket is attachable. Each stability projection 5 s can be positioned between two immediately adjacent vertically spaced apart attachment protrusions 5 p and be configured for positioning adjacent to one or more of the positional openings 2 p to contact the front rail 2 between positional openings 2 p to provide additional stability for the attachment of the bracket 5 to the front rail 2 via the attachment protrusions 5 p.

When attached to the front rail via positional openings 2 p, each bracket can have its rear end 5 b positioned away from the front end 5 a. A length of the bracket body can extend from the front end 5 a to its rear end 5 b via an intermediate elongated portion 5 c of the bracket body. The second end 5 b can be positioned in a rear portion of inner cavity 1 y and be positioned to freely hang via the positional attachment the bracket 5 has to the front rail 2 via attachment protrusions 5 p being inserted into the positional openings 2 p. The rear end 5 b of the bracket 5 can freely hang and not require attachment to any side 1 d of the shelving unit or other element to support the position of the bracket 5 or shelf 3 that the bracket 5 may help support. In some embodiments, the rear end 5 b of the bracket 5 can include a hole 5 e.

In some embodiments, the hole 5 e of the second end 5 b of the bracket 5 can be configured to facilitate attachment of the second end of the bracket to another structure or to permit a cord to pass through the bracket 5. For example, the hole 5 e can be sized to permit a power cord or other type of wire to pass through the bracket 5. Alternatively, the hole 5 e can be sized to permit a fastener or sidewall attachment projection to extend through the hole 5 e to help attach the second end 5 b of the bracket to a rear portion of the shelf unit 1.

As may be appreciated from FIGS. 1-3 and 6, the brackets 5 can be attached to the front rails 2 so that the brackets 5 are hidden from view when a user faces the front opening 1 a. The brackets 5 can be positioned so that the front rail 2 blocks the brackets view unless a user peers at an angle through the front opening 1 a. The color of the brackets 5 can be selected to help further hide the appearance of the brackets 5 to further minimize their effect on the aesthetic effect of the shelving unit by being colored the same as the color of the interior face of the sidewalls 1 d and front rails 2.

Each shelf 3 can include front corners 3 a defined at the front right and left edges to facilitate positioning in the inner cavity 1 y on a set of aligned brackets 5. The front corners can define a space for mating with a portion of the front rails adjacent the left and right sides of the article of furniture 1 for a relatively tight interference fit. The position of each shelf 3 can be maintained by the bottom of each shelf 3 contacting a top side of a pair of corresponding brackets 5 that are vertically aligned brackets attached to the right and left side front rails 2. It should be appreciated that the embodiment shown in FIG. 1 has three pairs of corresponding brackets 5 that each support a respective shelf via their attachment to the front rails 2 at different vertically aligned and spaced apart locations. Each of these locations is defined by a respective set of positional openings 2 p defined in the rear face of the front rails 2 as may best be appreciated from FIGS. 2-3 and 6.

As discussed herein, other embodiments can utilize less than three shelves and more than three sets of brackets 5. As another alternative, other embodiments can use less than three shelves and utilize less than three sets of brackets 5.

It should be appreciated that embodiments of the article of furniture and embodiments of the reverse cantilevered bracket assembly for a shelving unit can be configured differently to meet different sets of design criteria. The type of material the sidewalls 1 d, front rails 2, brackets 5 and/or shelves 3 are composed of can be any type of suitable material (e.g. metal, wood, etc.). The size and shape of each element can also be adjusted to meet a particular type of design criteria to provide a desired structural support and/or aesthetic effect. As yet another example, it is contemplated that a particular feature described, either individually or as part of an embodiment, can be combined with other individually described features, or parts of other embodiments. Therefore, while certain exemplary embodiments of the article of furniture and embodiments of the reverse cantilevered bracket assembly for a shelving unit and methods of making and using the same have been discussed and illustrated herein, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously embodied and practiced within the scope of the following claims.
